Mechanisms

The same few forces, everywhere they show up

The Fundamentals pages explain how things work. The Now pages describe what is happening. This page runs the connection in the other direction: pick a mechanism, and see every topic in the present where it is one of the forces actually doing the work.

It is worth saying what kind of index this is. It is not keyword matching - a page on shipping chokepoints does not use the phrase "network structure," which is exactly why the mapping had to be made by hand. Each entry below carries a specific sentence naming how that mechanism operates in that topic. Where the sentence is vague, treat the connection as weak.

Mind

Availability and salience

You judge how likely something is by how easily an example comes to mind, so vivid and heavily covered events feel far more probable than common quiet ones.

Explained in Biases
Mind

Confirmation and motivated reasoning

Evidence for a conclusion you want gets waved through; evidence against it gets audited. The extra scrutiny feels like rigor rather than bias.

Explained in Biases
Mind

Attention as the scarce resource

Attention, not information, is the binding constraint. Whatever competes for it is competing in a fixed-size market and will optimize accordingly.

Explained in Attention
Mind

Framing

The same fact changes what people decide depending on how it is worded, what it is compared against, and which category it is placed in.

Explained in Language and Communication
Mind

Intuition-first moral judgment

Moral verdicts often arrive before the reasons do, and much disagreement is about which concerns take priority rather than about facts.

Explained in Morality
Groups

Trust as a substitute for enforcement

Where people can be relied on, transactions are cheap. Where they cannot, the same transactions still happen - through contracts, auditors, escrow, and courts, all of which cost real money.

Explained in Trust
Groups

Norms and pluralistic ignorance

Most behavior is governed by unwritten rules that hold because everyone believes everyone else follows them - which is why they can outlive their support and then collapse in months.

Explained in Norms
Groups

The in-group boundary

Moral rules are applied fully inside a boundary and weakly outside it. Core prohibitions recur across societies; much of what varies is who is covered.

Explained in Group Identity
Groups

Status competition

Position relative to others is a genuine good people will pay for, and unlike absolute goods it cannot be increased for everyone at once.

Explained in Status
Groups

Network structure and cascades

Outcomes depend less on individual nodes than on how they are wired: hubs, weak ties, and the thresholds at which something spreads or stops.

Explained in Networks
Groups

The collective action problem

When everyone benefits from something whether or not they contribute, the rational individual move is to let someone else pay - so valuable things go unfunded without a mechanism that changes the payoff.

Explained in Cooperation and Competition
Groups

Social proof and cascades

People infer what is true and safe from what others are doing, so behavior can tip suddenly with no new information.

Explained in Influence
Economy

Prices as information

A price aggregates what millions of people know about scarcity into a single number. Suppress it and, as Hayek argued, that information degrades, while the scarcity resurfaces as queues and black markets.

Explained in Markets and Prices
Economy

Incentives and Goodhart's law

People optimize for what is measured and rewarded, not for what was intended. A measure that becomes a target tends to stop measuring what it was chosen for.

Explained in Incentives
Economy

Compounding and concentration

Returns that accrue to existing holdings widen the gap over time, so some concentration arises without anyone deciding it; whether a given level means something went wrong is disputed.

Explained in Wealth
Economy

Bargaining power inside a band

A wage sits between the most an employer could pay and the least you would accept. Where inside that band it lands is decided by outside options, not by merit.

Explained in Work
Economy

Transaction costs and the firm boundary

On Coase's account, activity is organized inside firms wherever giving an instruction is cheaper than negotiating a contract - so the boundary moves whenever coordination gets cheaper.

Explained in Firms
Economy

Comparative advantage and gains from trade

Both sides can gain from specializing even when one is better at everything, because what matters is relative cost - though the gains are usually diffuse and the losses concentrated.

Explained in Trade
Economy

Productivity as the ceiling

Output per hour sets the ceiling on average pay and on what a society can consume. For many economists, nothing else raises living standards as durably.

Explained in Productivity and Growth
Economy

Risk against uncertainty

Risk has a distribution you can price. Uncertainty does not. Treating the second as the first produces confident numbers that are wrong in the cases that matter.

Explained in Risk and Uncertainty
Economy

Path dependency and lock-in

Early choices constrain later ones. Systems settle into arrangements that are hard to leave even when a better option exists, because the switching cost is paid by whoever moves first.

Explained in Technology
Power

Institutions as persistent rules

Institutions outlast the people staffing them, encode the balance of power at the moment they were built, and are far easier to create than to redirect.

Explained in Institutions
Power

Legitimacy as coordinated expectation

Compliance rests on everyone expecting everyone else to comply. That makes rule cheap while the expectation holds and makes collapse sudden when it flips.

Explained in Legitimacy
Where it is doing the work
Trust and Legitimacy Falling institutional confidence is a change in what people expect of each other before it is a change in behavior.Authoritarianism and Democracy On the minimalist view of democracy, the critical moment is not the vote but the concession, and concession is a coordinated expectation.Russia Suppressing the expression of dissent also clouds the government's own reading of how much there is.China and the Reordering of Power Performance legitimacy holds while growth does; how much reserve it offers once growth slows is disputed.How Power Changes Hands Transfers happen without violence only where an agreed procedure is expected to be honored by the losing side.Religion and Power Religious legitimation supplies a claim that does not depend on this year's economic figures.Corruption Visible impunity corrodes more than visible corruption, because it attacks the claim that the rules bind at all.United States The page's two watch-curves are legitimacy itself: court orders obeyed and election counts conceded work only while each side expects the other to keep treating them as binding.Mexico The line Sheinbaum has drawn - no foreign military operations on Mexican soil - is a legitimacy constraint stronger than any statute; under steady US pressure, it has held through September 2026.Ukraine Martial law bars elections; the constitution extends the government's mandate, Moscow disputes it, and the usual tests of a government - a vote, a competitive media market - have been largely suspended since 2022.
Power

The principal-agent problem

Whenever one party acts on another's behalf, their interests differ and the principal cannot fully observe what the agent does. Every layer of delegation adds another gap.

Explained in Bureaucracy
Power

Credible commitment and the rule of law

People invest, lend, and trade across distance only if promises can be enforced against the powerful. A rule that binds only the weak is not a rule.

Explained in Law
Power

Agenda-setting

Research on agenda-setting finds that media coverage reliably shapes which issues people think about; evidence on how far it changes what they conclude is mixed.

Explained in Media and Information
Power

The security dilemma and escalation

Measures one side takes for defense are often hard to tell from preparation for attack, so both sides arm while both prefer that neither did.

Explained in Conflict

Two things are worth noticing after scrolling this. The first is how few distinct mechanisms it takes to cover more than fifty topics - which is the actual claim behind the name of this site. The second is that the topics with the most mechanisms running through them tend to be the ones where single-cause explanations feel most satisfying and are most likely to be wrong.
